Council of Ephesus

The Council of Ephesus was a church council held in present-day Turkey in the summer of 430 AD, with the Christian Church denouncing Nestorianism.

History
In 430, a church council convened in Ephesus denounced the teachings of Christian scholar Nestorius as heretical and against the true beliefs of the church. Nestorious argued - a little too loudly - that Christ had completely separate human and divine aspects to his nature.
